Study on technical conditions for mobile communication systems utilizing 700/900MHz bands

In Dec. 2009, Telecommunications Council under MIC started the following studies;


Followings are taken into account:- Effective frequency arrangement utilizing 700/900MHz bands - Conditions to coexist with other systems for the introduction of the mobile communication systems utilizing 700/900MHz bands

Spectrum bands of 700/900MHz (scheduled to be available after July 2012) are considered - 700MHz band will be available after the termination of analog broadcasting - 900MHz band will be available after the reallocation of mobile phone frequencies in 800MHz band



According to results of the study, the Telecommunications Council issued the partial final report on 17th May, 2011

The report concludes that LTE FDD, W-CDMA/ HSPA, HSPA Evolution and DC-HSDPA are technically applicable in 900 MHz band in Japan

Study result of 700 MHz band will be reported at later occasion because further study will be needed

ARIB had submitted the input contribution on this issue to 3GPP TSG-RAN#51 and RAN WG4#59 as information

Introduction of 3.9G system in Japan

In 2008, Telecommunications Council under MIC has conducted the following studies;

• Study on technical measures for the enhancement of the third-generation mobile communications system

• Study on conditions to coexist with other systems for the introduction of the enhanced third-generation mobile communications system

• Spectrum bands of 2GHz, 800MHz, 1.5GHz and 1.7GHz considered

Candidate Enhanced Systems (FDD) studied by the council including 3.5G

• LTE, UMB and Mobile WiMAX for 3.9G system

• Note: Mobile WiMAX was studied, but was not included in the final report because its FDD mode specs had not been completed yet

• HSPA Evolution and DC-HSDPA for enhanced 3.5G system
